How to Ferment Apples – Packed with Probiotics!
Introduction
Fermenting apples is a simple yet powerful way to turn a seasonal fruit into a probiotic-packed snack or ingredient. This technique enhances the flavor of apples, introduces a pleasant tanginess, and infuses your diet with beneficial bacteria that support gut health. Ideal for anyone wanting to boost their nutrition in a fun, hands-on way, fermented apples are a standout choice for healthy meal prep and creative snacking.
Why Fermented Apples Are the Perfect Healthy Snack
What sets fermented apples apart is their bright, tart flavor with just a hint of natural sweetness—plus the probiotic benefits that come from the fermentation process. They’re crunchy, tangy, and endlessly customizable with spices like cinnamon or ginger. Beyond taste, these apples are a great addition to salads, yogurts, or charcuterie boards, making them a crowd-pleaser for health-focused meal planners and food lovers alike.
Fermentation Basics: How Probiotics are Created
During fermentation, the natural sugars in apples are consumed by beneficial bacteria, resulting in the creation of organic acids and probiotics. The process requires little more than apples, water, and salt—nature does the rest! These bacteria support digestive health and can help balance the gut microbiome.
Easy Steps for Fermenting Apples at Home
Start by choosing crisp, fresh apples—varieties like Honeycrisp or Fuji work well for both flavor and texture. Slice the apples, submerge them in a simple brine, then let them rest at room temperature for a few days. The result? Delicious, probiotic-rich apple slices with complex flavor and satisfying crunch.
Tasty Ways to Enjoy Fermented Apples
Serve fermented apples as a snack straight from the jar, add them to sandwiches for a tangy crunch, or chop and toss into slaws and salads. They’re also a great way to add interest and probiotics to cheese and charcuterie platters, or use them as a topping on yogurt or oatmeal.
Nutritional Information and Serving Size
One serving (about ½ cup) of fermented apples typically offers around 25–35 calories, depending on apple variety, with zero fat and a healthy dose of fiber and beneficial probiotics. It’s a nourishing snack that supports digestive health while satisfying your craving for something crunchy and flavorful.

Instructions
- Wash apples thoroughly and slice into wedges or rounds, removing seeds but leaving the skin for maximum probiotics and fiber.
- In a bowl, dissolve the salt in 2 cups of filtered water to create your brine.
- Place apple slices and any optional spices into your sterilized jar, packing them tightly but leaving an inch of headspace at the top.
- Pour the brine over the apples, ensuring they’re completely submerged. You can use a clean weight (like a small glass or a fermentation weight) to keep them under the liquid.
- Seal the jar loosely so gases can escape (you can use a fermentation lid or simply set the lid on top without tightening).
- Store the jar at room temperature, out of direct sunlight. Let ferment for 3–5 days, checking daily. When apples reach your desired tanginess, move the jar to the refrigerator to slow fermentation.
- Enjoy your probiotic-packed apples chilled! They’ll keep in the fridge for several weeks.
